How to use a hole saw to cut metal with a cordless drill

[@Pro1er]

I've been following you for years and always enjoy your videos. I bought (what looks like), that same Dewalt 3-speed hammer drill about 20 years ago and still use it sometimes - that was a quality machine! Mine came with a side handle which I highly recommend when using a hole saw to spare your wrist in case of a jam. I also find that if you run the drill at too low of a speed it can over heat the motor. The motor is designed to run at 18 volts so running it at too low of a speed can cause it to work harder, plus since the motor is fan cooled, the fan needs to be spinning at a good rate to move enough air to keep the temperature down. For long jobs, every once in awhile, remove the drill from the work and run it at full speed to cool it down.

[@ultimatehandyman]

Yes, this is one of the best drills that I have ever owned. Thanks for the tips and the comment 👍

[@fastbike9845]

Motor will be running at usual speed, the gearbox slows down the chuck.

For weeks I had been putting of drilling a hole through the housing of a heating unit. (I was a bit intimidated by the task.) Today I watched your video, picked up some lubricant and went to work on the housing. It went perfectly. Thanks for the video.

You are welcome. Thanks for the comment and well done ;-)

[@24jh42]

He is forgetting the most important part of drilling with a hole saw. Every so often disengage the pressure and pull it out. Use a brush to remove the chunks of steel clogging the teeth of the saw.

[@jerrelCbanks]

Absolutely critical when drilling deep metal holes, a little jet of air or liquid helps get the debris out of the groove as well.

[@samazzer4507]

This video helped me so much. I had ordered a metal media console from ETSY. They were supposed to drill holes but they did not. So I watched your video over and over and over again. Especially the torque. My drill was not as good as yours and I upped the torque and there was blow back on my hand so I put it back to the number that you stated. I ordered a Klein tool for the punch (did not work that well and danced on the 3rd hole that I drilled. I also purchased 2 in. Xtreme Tri-Cut Tungsten Carbide Hole Cutter and so glad I did. And some cutting oil. I have never did anything like this before and am so Thankful for your video. I watched it again just before I started and caught something that I would have done wrong. The Klein tip did not work as well your your punch too. This was the time when I wished I would have purchased a better drill. By the 3rd hole that I was working on, I was toast but I drilled slow and steady. :)

1:10 other video show to put the machine on lower (not lowest) speed for smaller diameter holes, which is correct now ?

[@ultimatehandyman]

The larger diameter of the hole saw- the slower you need to go 👍

[@ReadyUpGo]

After your pilot hole is drilled and you’re ready to drill through, gently lower the teeth of the hole saw until they cut into the piece just enough to define the circle. Now drill a 3/8” hole inside your target diameter but right up to the outer rim of the hole you will be drilling. That will allow chips to drop down and lessen both the heat created from friction and the wear on the the teeth of the hole saw. Hope that makes sense.

[@terencebigt3825]

I want to drill about a 2 inch hole into a speaker grill on my motorcycle to mount 2 inch tweeters . Is this the same process? Steel mesh speaker grill.

[@ultimatehandyman]

No, you have to be really careful with mesh, the hole saw teeth can bite into it and rip it. The only way to successfully cut holes in some mesh is to firmly clamp it between two pieces of timber etc. Then cut straight through one piece of timber and the mesh, until you get into the last piece of timber. There are a lot of variables though with mesh size and teeth size on the hole saw, so sometimes it might be possible to cut right through it, without the timber.

I’ve got 4 holes to drill through 10mm steel. Is it worth trying with a hole saw or should I buy a rotabroach?

A decent holesaw will do it, but if you have a mag base drill the rotabroach will be much easier and quicker.

[@mitbener6805]

@@ultimatehandyman My dad has a mag drill. But I’d have to buy the new bit. Whereas I have the holesaw already. Thanks for your video, I’ll give the holesaw a go.

[@bendude6748]

Would one of these hole saws go through a 15mm thick piece of metal plate?

[@ultimatehandyman]

Yes, providing it is only mild steel or aluminium etc. You would have to go slow and use plenty of lubricant.

[@bendude6748]

Yeah it's mild steel, thanks for the quick reply!

[@TheFalconJetDriver]

I would also suggest removing the swarf (chips ) frequently by removing the hole saw clearing them from the hole, and use lots of lubricant. And go slow. High speed only heats up the hole saw. If you can find a carbide tipped hole that would cut much better.

[@dekurvajo]

I do this quiet often, but never on a vise. I put a plywood underneath the sheet, and firmly clamp it down on a table horizontally. Its way more safe, way more efficient, and the lubricant also stay as it suppose to lube. On the half way down i flip the metal, and start form the other side. So i don't let the friction slowing down the process, i give less torture to the saw-bit and the drill as well. Yes i know there will be a tiny rim in but thats not a big to get rid of it if its really wished.

[@ultimatehandyman]

Its a Bosch Bi-metal holesaw. They can be used on metal or wood, but wood tends to make them blunt.

[@christinechristine7283]

There is no reason for drilling it horizontally apart from it won't fit in the vice the other way around.

[@donaldshimkus539]

A hole saw blade may grab when it first engages the material being cut often breaking the pilot bit. I dill the pilot hole first then engage slow and careful. But the most helpful tip is to install a 1/4" rod in place of the pilot bit. Drill pilot hole with a separate 1/4" bit, then use the hole saw with the rod as a pilot. It's alot cheaper than buying a buch of pilot bits.

[@ultimatehandyman]

I'm not sure, it will definitely cut thin wall tubing, but because ducting is so large you would not be able to go straight through in one cut, so you might have to make a cut, then stop the saw and rotate the ducting.

You can get an arbor called an "oops arbor" , which allows you to use two holesaws on the same arbor, this means you can put a holesaw of the diameter of the original hole, then the larger diameter holesaw that you require on the same arbor for enlarging holes like this.

[@ultimatehandyman]

Neil George You are welcome Neil. I have been doing a few holes in stainless on site and got sick of nearly breaking my wrists so started to use the torque control- it worked well ;-)

[@disconeil]

In stainless??? Rather you than me mate. Are you a fitter in a Steelworks? the reason I ask is although you have a Lancashire accent (I know there isn't a strong steelworking area around there) alot of the tools you use are similar to the ones I see the fitters using around the mill. N.

[@ultimatehandyman]

Neil George I subcontract as a maintenance engineer at two local chemical plants, one of the plants has had a new production line installed and I have done quite a bit of installation/remedial work on it. Most of the machines are stainless including the wall partitions and control panels, so I have had to get the hole saws out a few times! Thanks for the comments ;-)

[@disconeil]

I reckon you really are an asset to them, your knowledge seems endless. I have learnt more from your channel than 13 years in education. Thanks alot mate. N.

[@ultimatehandyman]

Neil George Thanks Neil, I have learnt a lot from the people I work with when I am on site ;-) You are welcome and thanks for the comments

[@alianildinler]

low feed, high speed and cooling, nice work old man.

Can you cut metal with a diamond grit hole saw

[@ultimatehandyman]

jeales895 I'm not sure. I don't ever recall seeing one being used on metal to be honest, they are normally only used on Plastic/Tiles and masonry etc.

[@caskwith]

You will probably generate too much heat using a diamond saw, when the diamonds get hot they will actually dissolve into the steel and thus the bit will be ruined. Save them for tiles, masonry etc as noted above. Only exception to this is very very thin sheet metal, standard hole saws are too coarse for this so you can use a diamond grit saw, use a cheap one and take it slow, plenty of water as lubricant/coolant.

[@ultimatehandyman]

caskwith Thanks for the detailed comment ;-)

[@marcpadilla1094]

impressive. Although it took alot longer than the video shows.Lubricant and proper torque seem to do the trick.Well done.

[@ultimatehandyman]

Thanks for the comment

Down to earth chap, no hype, wonderful.

[@MegaBoossss]

Is that a regular hole saw for wood?

[@ultimatehandyman]

+Ty Osman It's a regular bi-metallic hole saw which can be used on wood or metal. Thanks for the comment

[@Wclifford7]

The Saw teeth tends to lock up when the hole saw teeth are almost through the sheet or when some to the teeth has cut through. Is it advisable to start at the other end at this stage or make a starter cut from both sides?

[@ultimatehandyman]

+Winston Clifford Yes, you can do that ;-)

[@muskokamike127]

I do that often to help remove the plug out of the hole saw if I don't need an absolutely clean hole.....quite often the pilot hole has enlargened slightly so when you drill through the other side, the two holes don't line up and you get a small ridge in your hole. If you want a nice clean hole, drill through from the one side. This is what I have found anyways, never tried drilling steel with a hole saw, just maple which is pretty damn hard in itself....

[@markschiavone8003]

Ultimate Handyman that hole saw looks like a wood cutting hole saw.

[@ultimatehandyman]

They can be used on wood, but are mainly for metal use. Thanks for the comment

[@markschiavone8003]

Ultimate Handyman so it's a hole saw specifically for metal?

[@dennisthedog4015]

So what am i doing wrong then

[@ultimatehandyman]

Not sure, just make sure that you use good quality hole saws ;-)

[@dennisthedog4015]

@@ultimatehandyman it was me ive had success. Thank you for the video and responding.

[@peterowens290]

All round a good practical demo of how to do it - Thanks

[@ultimatehandyman]

You are welcome. Thanks for the comment

[@CatNolara]

Small tip: drill a through hole right on the inside of the ring you are cutting. That way the chips get pushed out on the backside rather than clogging the saw.

[@ultimatehandyman]

Thanks for the comment 👍

[@milesparris4045]

Ideally you want to drill your pilot hole out to 1/4" and replace the drill in the hole saw with a 1/4" rod. This is stronger and keeps the flutes of the drill from enlarging the hole which will widen the hole saw path and make your drilling time longer.

[@stevenrolfe1918]

I would disagree with your comment about the coolant, it perhaps aided cooling a little but it’s more for lubrication to prevent friction etc ..

[@FrederSnorlax]

I drill a lot of holes in steel with a cordless. Thickest I’ve done is half an inch - i prefer a hole saw over a twist bit as it means moving less material. I found this video while looking for tips on keeping teeth from breaking on my carbide hole saw. (It cuts faster but is more expensive) For lubricant i use gear oil or soap. Yes, soap. It sounds weird but it’ll work better than most oils for tapping small things.

[@ultimatehandyman]

[@hozerdude]

what type of hole saw did you use to cut that metal? I need to cut thru some stainless steel that .025 thickness.

[@ultimatehandyman]

+Ron Davis Stainless is a real pain, so ensure you use the torque control and plenty of coolant/lubricant as it can snatch violently. The holesaws that I used were Bosch Bi-metal. Best of luck with it ;-)

[@marcussatterwhite]

Great video! Right on!👍👌👊👍👌👊👍👌👊

[@samp1394]

How much does that can of lube cost ?

[@ultimatehandyman]

It was only a couple of quid and has lasted me over 6 years LOL

[@fredjones5327]

Awesome video bro!!!!! I need to do this to the strut tower on my car, what dewalt drill is that???

[@ultimatehandyman]

It's a Dewalt XRP 18v drill (the one with the fully metal chuck), I can't remember the model number, sorry. Thanks for the comment 👍

[@fredjones5327]

Ultimate Handyman Yw brother!!!!💪🏽💪🏽 and thanks!!!

[@aytviewer2421]

Thank you so much for this video. I need to drill a hole in metal exactly like this. I never knew about putting the drill into torque mode when using hole saws. Luckily, the metal I'm drilling into is only about 2-3 mm thick, so I'll have an easier go at. Cheers!

[@ultimatehandyman]

Thanks for the comment 👍

[@terrablader]

I got it in the ribs when I tried this without torque selector
